Abstract
To provide a simply-structured multilayer electrostatic actuator that exhibits a sufficient stroke and a sufficient contraction force in a specific drive range, and rapidly hardens upon an attempt to widen the interval between electrodes beyond the drive range. A multilayer electrostatic actuator (1) is configured by a plurality of actuator parts (2a, 2b, 2c) each including: a first film (3a1, 3b1, 3c1) having a plurality of first connection regions (7a1, 7b1, 7c1) formed on one surface in a predetermined pattern; and a second film (3a2, 3b2, 3c2) connected to the first film via the first connection regions, and having a plurality of second connection regions (7a2, 7b2, 7c2) formed on a surface opposite to the first film in the identical pattern. The actuator parts are connected and layered via the second connection regions. On both the first film and the second film of one actuator part (2a, 2b, 2c), a non-connection region (15) is formed having a substantially fixed width between connection regions adjacent to each other as viewed in a layering direction (Z). The first connection regions and the second connection regions are arranged so as not to overlap each other as viewed in t…
